History and significance of World Metrology Day
World Metrology Day was established at the 21st General Conference on Weights and Measurement in October 1999. May 20 was chosen as the day to celebrate Metrology day because this day marks the signing of the Metre Convention on May 20, 1875. The day is considered to be the initiation of the formal international collaboration. On the Metre convention meet, 17 nations signed the treaty namely the US, Portugal, France, Venezuela, Germany, Italy, Russia, Austria-Hungary, Denmark, Sweden, Switzerland, Brazil, Argentina, Belgium, Peru, Norway and the then Ottoman Empire.
The treaty played a vital role in building a global standard and uniformity in the measurement units. It also led to the formation of the BIPM, which includes 59-member intergovernmental organisations, and the International Bureau of Weights and Measures.
